PB69 PolyBak backer from Richwood Industries is a brown .020 inch thick sheet in a 37 x 1800 inch format, which gives fabricators a consistent backer layer for large panel runs and long continuous layups. This PB69 material is 2.5 times stronger than the leading saturated Kraft paper backer of the same thickness, so it resists tearing and damage while panels move through press cycles and shop handling. The PB69 construction is designed as a backer for laminated substrates, which helps balance laminated faces on panels during normal service. As a paintable overlay for substrates, PB69 provides a prepared surface so the panel back can be finished to match project needs. PB69 is also used as a paintable overlay for columns, allowing curved or vertical elements to share the same backer system as flat laminated work.
This PB69 PolyBak backer is most commonly used as a backer for laminated substrates, so it fits naturally into standard lamination presses and adhesive workflows. Its role as a good wood veneer balancer supports veneer-faced panels by giving the back side a dedicated balancing layer during pressing and later machining. When used as a paintable overlay for substrates, PB69 provides a surface ready for finishing operations behind decorative faces. In column applications, its paintable overlay function helps installers and fabricators carry the same backer system from flat work onto vertical or rounded structures.
PB69 PolyBak backer is most commonly used as a backer for laminated substrates, providing the counter layer that laminated faces need so the sheet performs consistently in regular service. Its designation as a good wood veneer balancer means it works on veneer-faced panels that benefit from an engineered back side to offset the veneer face. As a balancing backer, PB69 supports flatness by contributing a predictable layer on the reverse of workpieces. Because it also functions as a paintable overlay for substrates, this same sheet can serve cabinet backs, casework, or other laminated components that require a finish-ready back surface.
The fact that PB69 is 2.5 times stronger than the leading saturated Kraft paper backer of the same thickness gives shops a tougher backer when panels move through presses, saws, and routing operations. That added strength helps panels carry through handling and machining with less risk of back-side damage during normal workflow. The .020 inch thickness matches the intended PB69 build, so the balancer layer aligns with standard laminated constructions. With a 37 x 1800 inch format, this PB69BR28-37X1800 PolyBak backer roll supports repeatable cutting patterns and continuous runs, which streamlines panel nesting and reduces waste in shop production. Using one PB69 material as both a balancing backer and a paintable overlay for substrates and columns also simplifies material selection across related components.
The PB69 PolyBak backer is 37 inches wide by 1800 inches long at .020 inch thickness, which supports long production runs and consistent panel sizing.
This PB69 PolyBak backer is most commonly used as a backer for laminated substrates, providing a balancing layer behind the decorative face during lamination.
PB69 works as a good wood veneer balancer by supplying a dedicated back layer that counteracts the veneer face on panels during normal use.
Being 2.5 times stronger than the leading saturated Kraft paper backer of the same thickness gives PB69 added resistance to tears and damage during handling.
PB69 PolyBak backer is used as a paintable overlay for substrates, so the back face can be finished to project requirements.
PB69 is used as a paintable overlay for columns, allowing vertical or column elements to share the same backer system as flat laminated panels.
Choose this PB69 PolyBak backer from Richwood Industries when a brown .020 inch, 37 x 1800 inch sheet fits your laminated substrate workflow. Its use as a balancing backer, wood veneer balancer, and paintable overlay for substrates and columns allows one material to support multiple panel and column tasks in the same project.
